Real-time Call Conversion and Transcoding
Utimaco LIMS Gateway
The Utimaco LIMS Gateway is a powerful, yet cost-effective media gatewayappliance fully integrated with the Utimaco Lawful Interception Management System (Utimaco LIMS).
The LIMS Gateway converts intercepted calls between SS7/ISDN and VoIP networks. It supports all common voice codecs including transcoding and protects calls by comprehensive access control and encryption features.
In combination with Utimaco LIMS the gateway mediates intercepted calls in compliance with common LI standards, such as ETSI TS 102 232-5 and TS 101 671.
